Generalized Hanbury Brown-Twiss effect for Stokes parameters

David Kuebel, Taco D. Visser

Abstract

We show that both the Hanbury Brown-Twiss effect and scintillation are just two manifestations of a wider class of Stokes fluctuation correlations. These correlations are not independent, but satisfy certain sum rules. This leads to the possibility of scintillation squeezing.

Generalized Hanbury Brown–Twiss effect in partially coherent electromagnetic beams

Gaofeng Wu, David Kuebel, Taco D. Visser

The recently introduced concept of Stokes fluctuations generalizes both the Hanbury Brown--Twiss effect and the notion of scintillation. Here we apply this new framework to the specific example of a Gaussian Schell-model (GSM) beam. We derive formulas for Stokes scintillations and Stokes fluctuation correlations, which explicitly express the dependence of these quantities on the GSM source parameters. It is found that the normalized Stokes scintillations vary significantly with position. Also, they can be either positively or negatively correlated.

Polarization and Coherence in the Hanbury Brown-Twiss Effect

Xianlong Liu, Gaofeng Wu, Xiaoyan Pang +2 more

We study the correlation of intensity fluctuations in random electromagnetic beams, the Hanbury Brown-Twiss effect. Not just the state of coherence of the source, but also its state of polarization has a strong influence.

Polarization and coherence in the Hanbury Brown–Twiss effect

Xianlong Liu, Gaofeng Wu, Xiaoyan Pang +2 more

We study the correlation of intensity fluctuations in random electromagnetic beams, the so-called Hanbury Brown–Twiss effect (HBT). We show that not just the state of coherence of the source, but also its state of polarization has a strong influence on the far-zone correlations. Different types of sources are found to have different upper bounds for the normalized HBT coefficient.

Hanbury Brown Twiss Effect for Ultracold Quantum Gases

We have studied two-body correlations of atoms in an expanding cloud above and below the Bose-Einstein condensation threshold. The observed correlation function for a thermal cloud shows a bunching behavior, whereas the correlation is flat for a coherent sample. These quantum correlations are the atomic analog of the Hanbury Brown Twiss effect. We observed the effect in three dimensions and studied its dependence on cloud size.

The influence of the degree of cross-polarization on the Hanbury Brown-Twiss effect

We show by example that correlations between intensity fluctuations at two detectors generated by two beams may be different, even if the beams have the same degree of coherence and the same degree of polarization.

EPR Correlations as an Angular Hanbury-Brown--Twiss Effect

Aloysius F. Kracklauer

It is shown that EPR correlations are the angular analogue to the Hanbury-Brown--Twiss effect. As insight provided by this model, it is seen that, analysis of the EPR experiment requires conditional probabilities which do not admit the derivation of Bell inequalities.
